Since the the world's leading smart phone maker confirmed it would have the flexi-form smart phone on the shelves early next year, developers and consumers have been itching to pick up any morsel about the ground-breaking device.

While it sounds like engineers are still ironing out some of the technical kinks, the user experience is fairly firmly set, Samsung was happy to confirm at the Samsung Developer Conference in San Francisco to a small audience of developers.

In Samsung's words the "main display" is a richer and more immersive experience. Broken down - you are actually getting almost double the screen real estate at 7.3 inches, and the option to run three apps simultaneously side by side, like separate windows.

The literal jump from the cover display when you open to the main display is intended to be seamless - so that the user can continue what they're doing once they've unfolded.

For example if you are using a navigator map on the cover display to find directions, when you flip the phone open, the same place in the map will show up on the main display inside without interruption, but with a larger surface area to include more of the map.

While Samsung was happy to give away certain specifications so developers could get moving on building apps to service the specialist multi-screened phone, there were some important things they remained tight-lipped on:

So what about...?

Camera:

Where the camera will be placed on the phone was still in the works, according to Mr Park.

Price:

Samsung Mobile Engineering Director Jisun Park said the price was not determined yet, but that it would be "as appropriate as possible."
